Help pls

Ladies I'm in a LDR he lives an hour and a half away and I miss him like crazy. We see each other often but lately His lifestyle is completely different from mine and hes constantly working but I miss him like crazy. I admire his dedication for work and making ends meet and taking care of his family I love that. I'm very family oriented myself so I totally understand him but I miss him and I can't stop thinking bout him and wanting him near and just being able to talk to him. However he allows himself to become so busy and involved with his life and what's around him that he goes around 2-5 days without talking to me. And I can't help but think if he's losing interest or he's sincerely busy or just cheating on me. I know y'all ladies say to trust and all that but we've gone through a lot and we are working on it but yeah any help?
